Oily lubricants can resist heat, viscosity, corrosion control, the stability of oxidation, and even the handling of water!
The definition of lubricant is a substance, usually liquid, application of which can reduce friction between two close surfaces. It is used to decrease the friction between these surfaces thereby decreasing the probability of wear and improving efficiency. The term lubricity is used to describe the ability of lubricants to lubricate moving components and subsequently reduce the friction that results. There are specialty lubricants that are formulated to dissolve foreign debris and contaminants, and are also used in the transferring of heat. Most of the industries also apply to practical use these lubricants so as to adjust to different operational situations, to cope with the various requirements of the equipment and also for specialized processes. To fully appreciate its uses and understand how it can be applied; a complete understanding of the additional properties of lubricating oil is required.
Capacity to shed heat
When two objects rub against one another, friction is created and, consequently, heat results from the friction. As a result of a natural reaction, lubricating oil must remain stable even if it is exposed to heat from different operations and various types of conditions. If the lubricant is not resistant to heat, oxygen can enter the mix and new compounds will be formed. A common compound that can cause damage to a variety of metal surfaces is carboxylic acid. Because of lubricating oil's ability to resist heat, it is best used for systems that are at high risk of breakdowns caused by heat or thermal failures.
Viscosity or a measure of the resistance of a fluid
Viscosity is a measure of a fluids dynamic properties. You will typically find that the viscosity diminished when lubricating oil hits a higher temperature. The property can be changed so that the viscosity range will stay within limits despite temperature and/or environmental changes. The lubricating oil's viscosity is also used to determine how thick the layer of the oil is in between metal components during reciprocal motion.
Corrosion-control ability
Specially formulated lubricants will usually contain detergents which will slow the formation of oxidants and corrosive deposits. The property of lubricant oil to control corrosion is a fundamental objective of lubricant formulation. This corrosion resistance forms vital seals around surfaces and protects from corrosion.
The stability of oxidation
The rate of oxidation is inhibited by most lubricant oils. Many powerful lubricant oils sold commercially are especially formulated to withstand the oxidation process. A couple of examples would be turtine and synthetic lubricating oils.
Handling water
In motionless environments and situations, it is necessary for lubricating oil to drip water. Diminishing or faltering effectiveness of the oil's properties could be formed when lubricant oil has a decreased water-handling capacity. Also there might be a risk that emulsions may form.
One would be hard-pressed to find an industry which does not use lubricants. The different properties of this substance can contribute to significant effects in the operations where they are applied.
